An unprecedented indium-promoted three-component 1,3,4-trifunctionalization cascade of 1,3-enynes with sodium sulfinates andtert-butyl nitrite (TBN) to access 5-sulfonylisoxazolesvia[3+2] annulation is reported. By employing TBN as both the radical initiator and the N-O two atom unit, this method enables the formation of three new carbon-heteroatom bonds, C-S, C-N and C-O bonds, in a single reaction through a sequence of sulfonylation, isomerization, nitration and annulation with a broad substrate scope, excellent selectivity and the potential of late-stage functionalization of natural products.

The cycloaddition reactions of (phenylsulfonyl)-1,2-propadiene (1) with various 1,3-dipoles have been investigated.MNDO calculations suggest that the reaction of the activated allene will proceed in a highly regioselective fashion and undergo cycloadditio
